日期控件使用说明：

1、 onClick='setday(this);'   －－ 此方法系统默认，时间格式为'yyyy-mm-dd'

  
2、 onClick='setday(事件框ID,日期显示目标框ID,'时间格式');' －－ 此方法是默认方法的扩展
  
参数说明:

事件框:比如你要点击一个ID为test的INPUT,那么事件框为INPUT的ID
  
日期显示目标框:指时间显示哪个地方;比如:用户点一个按钮时把时间显示在一个INPTU框中,
那么目标框就是INPUT的ID,如果显示本框为this

时间格式: 时间格式为'',则默认'yyyy-mm-dd'
其他支持: yyyy-mm-dd yyyy-mm yyyy/mm/dd yyyy/mm 等,一般常用的都支持
  
实例1:<input type="text" id="test" onclick="setday(this,this,'');" />
一般会在这个INPUT里显示时间格式为yyyy-mm-dd

实例2:
<input type="text" id="test" />
<input type="button" id="b" onclick="setday(this,test,'');" />
点击按钮,会把时间显示在TEXT框中.
  
此控件由网上找到,根据自己使用不同,进行了修改,并其实更加简单,使用方便,参数减少
